Bike lanes, rental docks, repair stands, bicycle shops, e-bike chargers, parking and drinking fountains are all mapped in this Dortmund cycling infrastructure map, shown as points, heatmaps and a 300-metre accessibility zone around the cycle network. 3D buildings, city sights including Signal Iduna Park and a guided story reveal which sub-districts are truly bike-friendly. Mobility planners, bike-sharing operators and cycling advocates in Germany can benchmark their own city against it.
